What is CDN?
CDN is the short acronym for Content Delivery Network, and it represents a large network of servers that are spread across different geographical locations. The main purpose of these servers is to cover a territory well and provide fast answers to the requests of potential users. All of the servers store the needed information, like images, video, code, in their cache memory. Additionally, they aim to be as close as possible to the users. As a result, the service is way more improved and quicker. Moreover, an extra positive effect of the CDN is load balancing. It improves the performance and reduces the load on the primary server.
